IMPROVEMENT IN JAPANNED LEATHER- l'he schedule refen'ed to in theseLetters Patent and making part of the lame.

T 0 all persons to whom these presents may come:

Be it known that I, FRANKLIN S. ll/IERRITT, of Boston, Massachusetts,have inventcda new and useful Improvement in the Manufacture of JapannedLeather; and do hereby declare the same to be fully described asfollows:

1 The object of my invention is the production of a new manufacture, orjapanned leather in imitation of alligator-skin.

The process of manufacture is as follows, viz.:

The Leather is prepared by the ordinary process of currying for patentor enameledleather. Afterward it is to be coated with a composition oflinseed-oil 'hoiled with driers, viz., litharge, burnt or raw umber,sugar of lead, sulphate of zinc, Prussian or Ohincse blue, mixed withnaphtha, benzine, spirits of turpentine, or camphine, with suificientlamp or ivoryblack to give it coloring. v

The leather, after being coated with several layers of the composition,each being' dried before the next is applied, is to be rubbed withpumice-stone to give,

a smooth surface to the coating. Finally the last layer is to be appliedand dried withoutrubbing with pumice-stone, the whole making, thus far,what is usually called patent or enameled leather. The leather in thisstate is next-to be wet sufficiently to soften it to admit of itreceiving and retaining the impression of the die or rollers. Next thesheet of Ieather is to be passed between rollers or dies, or compressedby the same, so as to em'boss it with the required figure or series ofconvexities. Next it should be dried and afterward be softened byboarding, or by any other mode of efi'ectiug such as usually adopted byleather dressers.

Figure 1 of the accompanying drawing represents a face view, and

Figure 2 a section of a piece of leather made as described.

When finished it is much preferable to ordinary japanned leather formany purposes in the arts, partijcularly in the manufacture of shoes.'

I make no claim to plain-surface japanned leather made as hereinheforedescribed. The subsequent op- Witnesses R. H; EDDY, S. N. PIPER.
